Identifying and correcting non-constant variance in error terms.
As highlighted in the text, developing a reliable economic forecast follows a structured methodology: the properties of stochastic time series
The curriculum is structured around four primary quantitative fields: the properties of stochastic time series
This section is a standout feature, covering the art and science of analyzing data over time. It includes classic techniques like smoothing and extrapolation, the properties of stochastic time series, and detailed instructions for estimating and forecasting with ARIMA models as well as more modern methods like ARCH and GARCH****. the properties of stochastic time series
